### Method

# Gio DataInputStream read_until_async

deprecated: 2.56 since: 2.20

#### Declaration [src]

    void
    g_data_input_stream_read_until_async (
      GDataInputStream* stream,
      const gchar* stop_chars,
      gint io_priority,
      GCancellable* cancellable,
      GAsyncReadyCallback callback,
      gpointer user_data
    )

#### Description [src]

The asynchronous version of g_data_input_stream_read_until(). It is an error to have two outstanding calls to this function.

Note that, in contrast to g_data_input_stream_read_until(), this function does not consume the stop character that it finds. You must read it for yourself.

When the operation is finished, `callback` will be called. You can then call `g_data_input_stream_read_until_finish()` to get the result of the operation.

Don’t use this function in new code. Its functionality is inconsistent with g_data_input_stream_read_until(). Both functions will be marked as deprecated in a future release. Use `g_data_input_stream_read_upto_async()` instead.

Available since: 2.20

Deprecated since: 2.56

Use `g_data_input_stream_read_upto_async()` instead, which has more consistent behaviour regarding the stop character.

This method completes asynchronously. Use `g_data_input_stream_read_until_finish()` inside the `GAsyncReadyCallback` to obtain the result of the operation.

#### Parameters

`stop_chars`

`cancellable`

  Type: `GCancellable`

  Optional `GCancellable` object, `NULL` to ignore.

  The argument can be `NULL`.
  The data is owned by the caller of the method.

`callback`

  Type: `GAsyncReadyCallback`

`user_data`

  Type: `gpointer`

  The data to pass to callback function.

  The argument can be `NULL`.
  The data is owned by the caller of the method.
